// Sprint 10 Task F — close-out analysis on the 14-instance tri-vendor run.
//
// Reads the ensemble JSON produced by Task E and emits:
// 1. Overall Fleiss' κ (vendors only, vendors + PM).
// 2. Per-category Fleiss' κ (temporal-scope, null-result,
// chain-of-anchor, single-hop, multi-hop, open-ended).
// 3. Per-F-mode Fleiss' κ (F1, F2, F3, F4, F5, correct/null).
// 4. Per-vendor match rate vs PM labels across the 14-instance set.
// 5. GO/NO-GO signal per brief §pre-registered band (≥0.60 moderate
// floor authorizes Sprint 11 judge-methodology go-ahead).
